OIL BURNER.

Application filed June 26, 1923. Serial No. 647,862.

To all ywhom if; may conce/ra:

Be it knoivn that l, CHAnLns R. HorKrNs, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented or discovered certain new and useful Improvements in Oil Burners, of `which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improved oil burner for heating furnaces or the like, and the invention has for its object to provide a device of this kind which is of simple construction and effective in operation, and which provides convenient means for adjustment for regulating the discharge of the mixed air and oil according to conditions in the furnace, as will hereinafter more fully appear.

In the accompanying drawing Fig. 1 is a central section of the improved burner. Fig. 2 is an end view of the same looking from the left of Fig. 1, and Fig. 3 is an end vievv looking from the right of Fig. 1, showing the air adjustment disk.

Referring to the drawing, 12 denotes the burner head which is provided with tvvo oil inlet chambers 13 and 13, The oil feed pipe 141 communicates with the oil inlet chamber 13, said pipe being provided With a by-pass portion 14a communicating With the oil chamber 13a. By means of a valve 15 the oil feed may be directed into either the chamber 13 or the chamber 13a, as may be desired.

Bolted to the head 12 is a tapering pipe or nozzle 16, and arranged Within the chamber of said pipe or nozzle are tvvo sets of oil tubes 17 and 17at communicating with the oil chambers 18 and 13a, respectively. The pairs of oil tubes extending through the chambers of the nozzle 16 are arranged to converge at their outer ends, which are closely adjacent to the discharge end of said nozzle, as clearly shown in Fig, 1, the two tubes constituting each pair preferably having their outer ends formed, as shown in Fig. 1, so as to present flattened openings at their ends toward each other. The head 12 is provided with a central air inlet opening 18 which communicates with the chamber of the tapering pipe or nozzle 16.

Pivotally mounted on a bolt 19 supported at the outer or discharge end of the pipe or nozzle 16 is an air regulating disk 20 provided With a series of openings 21 of different sizes; and by turning the said disk so that any one of these openings comes opposite the discharge ends of the tubesl 17 and 17' the discharge from the chamber of the nozzle 16 may be varied as may be found desirable. For example, in starting a cold furnace large quantities of air should be used foi` the preliminary heating, but as the furnace becomes heated the quantity of air supplied may be reduced and yet the same results obtained at the tip of the burner. To efiect this result the air or discharge regulating disk 20 maybe turned on its pivot bolt I19 to bring an opening 21 of the proper size opposite the burner tip, the size of the opening .thus placed in use being suchv as may be found to be desirable, according to the temperature of the furnace.

In the operation of this improved burner oil under pressure Will be supplied to the oil feed pipe 141 and air under pressure Will be supplied to the air inlet 18. The oil will be discharged in a fine spray from the converging ends of the tubes 17 `and 17a according to Which pair of tubes may be in use.,

and the air under pressure passing the ends of these tubes Will cause a complete atomization of the oil so as to provide for efficient combustion of the mixture of air and atomized oil.

Screwed into the o-il chambers 13 and 13a are removable plugs 22 arranged opposite the connections of the tubes 17 and 17 a With the head 12. These plugs may be taken out When it is desired to clean out the oil tubes by inserting a Wire or the like through the openings normally closed by these plugs.

It is intended that ordinarily only one pair of the tubes 17 or 17a should be in operation at one time, and if any stoppage occurs in the pair of tubes Which may be in operation the valve 15 may be turned t0 deflect the oil feed into the other oil chamber in the head 12, and the oil tubes which may have become stopped up may then be cleaned out Without interrupting the operation of the burner.

The adjustable disk 2O may be secured in any desired position by the nut 19a on the pivot bolt 19, as Will be understood.

While, as just stated, one pair of the oil feed tubes will ordinarily be in use at one time, under certain conditions, it may be deemed desirable to have both pairs of tubes in use simultaneously, and in such case a three-way valve 15, of such construction as to permit the passage oi' oil to both oil chambers 13, 13a in the head 12, may be employed.

Having thus described my invention I claim and desire to secure by Letters Patent:

l. An oil burner comprising a chambered burner head and nozzle, combined with an adjustable regulating disk mounted on the discharge end oi said nozzle and having a plurality of openings of different sizes any one of which may be brought into register with said discharge end of said nozzle, said head having two oil inlet chambers, pairs of oil tubes in said nozzle, said tubes communicating with said oil inlet chambers and having converging discharge ends closelj7 adjacent to the outer end of said nozzle,'and oileed pipes communicating with said oil inlet chambers.

2. An cil burner comprising a ehambered burner head and nozzle, combined with an adjustable regulating disk mounted on the discharge end of said nozzle and having a plurality of openings of different sizes any one` of which may be brought into register with said discharge end, said head having two oil inlet chambers, pairs of oil tubes in said nozzles, said tubes communicating with said oil inlet chambers and having converging discharge ends closely adjacent to the outer end of said nozzle, oil 'feed pipes communicating with said oil inlet chambers, and removable plugs mounted in said head and closing openings permitting access to said. oil inlet chambers and oil tubes.

8. Ain oil burner comprisinga head having an air inlet and two oil inlet chambers arranged on opposite sides of said air inlet, a nozzle the chamber 0i which communi- Cates with the said air inlet in said head, outwardl)Y converging oil tubes terminating closely adjacent to the discharge end of said nozzle, said tubes communicating with said oil chambers in said head, and removable f plugs mounted in said head and closing openings permitting access to said oil inlet chambers and tubes.

In testimony whereof I affix my signature.
